" Patented June 2, 1942 UNITED STATES PATENT OFF-ICE a v 2,285,349 Y V STEAM GENERATING APPARATUS Antoni Muszynski, Southampton, Mass. Application June it, 1940, Serial No. 341,482

1 Claim.

My invention relates to improvements in steam generating apparatus and other types of water heaters and the principal objects of my invention are directed to the provision of a steam'gencrating apparatus which is characterized principally by its simplicity in design and by its efficiency of operation. v

In connection with pressing machines or the like, where steam is used, itis usually desired to produce the steam as economically andas efficiently as is. possible and to that end, the novel construction of my invention is adapted.

With the foregoing, and various other novel Figs. 2 and 3 are sectional plan views on the lines 2--2 and 3-3 respectively of Fig. 1.

Referring'now to the drawing more in detail, wherein similar reference figures refer to like parts, and referring more particularly to the preferred form of my invention which has been ner as bythe member 8. The said shell is spaced from the boileras shown so as to provide an upwardly extending annular space which actsas a pressure relief means for the gases when the burner is in operation. An upper wall It of the shell preferably extends in a converging relation towards a flue or smoke pipe l8.

The supports I0 forthe boiler and the. ring 8 with which they are associated are so arranged that an annular space I l is provided at the lower end of the boiler, as shown.

With the oil burner in operation, the hot gases pass upwardlythrough the boiler, for heating the water therein, to the stock IB. and'also upwardly through the space I l into and through the annular space and to the stack. The annular selected for illustrative purposes, I have shown a base which is represented by 2. This base has side walls 4 which may consist of a refractory of metal substantially as shown. A burner B is represented in dot-dash lines and this may be of any well-known form for delivering oil and air to the combustion chamber within the base 2.

A plate 6 on the upper side of the walls 4 has a central opening which is surrounded bya vertically disposedflange, substantially as shown. A ring 8 encircling the verticalfiange and resting upon the plate member 6 has a plurality of inwardly extending supports I 0 which are adapted for supporting a boiler l2 The boiler l2 may be of the tubular type and through its body the gasespass upwardly from the combustion chamber for purposes of heating the water contained therein.

Suitable pipes, such asl3, are associated with the boiler for conducting the condensate thereto and the steam therefrom. I

A shell [4 surrounds the boiler and is suitably space or passageway acts to relieve, excessive pressure when theburner is started to run;

The arrangement is such that a minimum of fuel is required for the volume of steam for a pressing machine or some like apparatus.

Not only is the water heated by the internal passage of hot flue gases but also the heat travels upwardly outside the boiler for transfer to the water therein.

If desired, the outer shell may be insulated so that the boiler retains heat and thereby contributes to the economy in operation.

Manifestly the specific details of construction may be considerably varied from those herein shown and described without involving any departure from the principle of the invention or sacrificing any of the advantages inherent therein. While I have described my invention in this specification in great detail and particularly with respect to the present preferred form thereof, it is not desired to be limited thereto since many changes and modifications may be made therein without departing from the spirit and scope of the invention.

The invention may be embodied in other specific forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claim ratherthan by the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claim are therefore intended to be embraced therein.

What it is desired to claim and secure by Letters Patent of the United States is:

Heating apparatus of the class described comprising in combination, a hollow base member formed to provide a combustion chamber having an open upper side, a plate member supported on top of said base member formed to have a vertically extending flange surrounding a central opening therein, an annular ring member having a vertically-disposed lower part encircling said flange and an upper part which flares inwardly and upwardly from the upper edge of said lower part above said flange and opening, a verticallydisposed tubularishell member having its lower marginal edge engaging said upper part of the ring member intermediate the upper and lower vertically disposed therewithin and providing a space therebetween, said boiler also being of such diameter that its perimeter is spaced from said upper marginal edge of the inwardly-flaring upper part of the ring member so as to provide a space therebetween which leads into the firstnamed space, and a plurality of separate supporting members extending inwardly towards one another from the inner side of said ring mem-- ber below the upper marginal edge thereof, the lower side of said boiler being supported by said supporting members and the latter being spaced apart to provide passageways leading from the combustion chamber to said spaces.
